Antacids: short-term relief for occasional heartburn

Antacids are usually chosen when occasional heartburn needs prompt relief. They can be practical after a clear trigger such as a heavy meal, but their effect is short and they are not the right fit when symptoms keep coming back week after week.

This category is easiest to compare by format, ease of use, and how well it suits the timing of the symptom. Some products also combine an antacid with an alginate layer, which can be useful when acid rises into the throat more than usual.

The main caution is interaction timing. Antacids can reduce the absorption of other medicines, so a clear gap is often needed. That matters especially if you use regular prescription treatment, iron, osteoporosis medicines, or antibiotics.

Seek care if you keep needing short-term relief repeatedly, symptoms return soon after self-care, or there is difficulty swallowing, vomiting, black stool, or unexplained weight loss. Read more: Acid reflux.
